In connection.` with the control hy the operator oit' a worleengaging ineinher which is also poWer-actuated, a` i'eature ot the. inrentiou relates to novel means tor permitting these movements to lie produced independently so that interference ot the respeetire aruating means with the movement pro duced by the other avoided.

The franie of the. inarhine consists of a rectangular hase. 29, from which rises a uilard 12;. inning a louer Aforward extension and an upper orerhauging arm 26. Cleats 27 iixed to the upper surface ot the hase in opposite pairs, and hy engageinent with grooves 25B in the 'foot of the standard and with the edges of said stand ard may position the latter in either oi' two positions at. right angles to one another. Vthe extension and arm are provided at their outer portions with lower and upper Ways l and QS. respectively. to receive interchangeably the Work-suppm-ting elements and nail-driving elements. depending upon Whether the direction of nailing' he down or up. At the lower portion of the rear ot' the standard are three horieoutall;v arranged pairs of reeesses 30. 32 and 24 into which may he bolted hearings to Carry actuating shafts extending either Vfrom the rear to the front of the machine or transversely thereof. depending upon the manner in Whirh it is desired to applyY power to the machine. The. recesses 30 receive the Inain power .shaft 36, While a seoondartxT shaft 3S may7 he supported in either the recesses 32 or 3i. according to Whether the :machine is to nail in a downward or upward direction. The frame is provided with various bosses, hearing sul taees and openings to facilitate. the attzuhincur. :and passage ot the actuating elements iu the didier-ent positions they7 will assume. for the diverse arral'lgeinents oi the machine. li Will iiret describe the organiz/.ation in Whieh the Worlt-supi'iortinfg and operating; inerhanisins are disposed for downward nailing' under the iniiuenee of aetuating shafts extending transverselyv oi the traine.
